  Actually, I wonder if this is the right thing to do... This is a 
userspace library that requires a platform-specific linux/xxx.h. For an 
external toolchain, these headers don't exist in
$(STAGING_DIR)/usr/include/linux

  Directly using $(LINUX_DIR)/include means that the headers are not 
patched for userspace. For those platform-specific headers that's 
probably not a problem, but it's not good for e.g. linux/types.h.

  An easy workaround is to use -idirafter instead of -I.  However, 
perhaps it's an even better idea to do 'make headers_install' as part of 
the normal linux build process, so that packages depending on those 
headers can use the patched version. But then again, is it a good idea to 
replace the toolchain's kernel headers with a new set of kernel headers?

  Any advice is welcome!

  Regards,
  Arnout
